### Step 2: Start Up and Home the CMM

Power on the controller and start PC-DMIS. After the machine moves to its home position and stops, you are ready to start the tutorial's first step.

#### More Info

You can use PC-DMIS with your CMM to develop measurement routines and then run those routines to inspect your parts. To use PC-DMIS with a CMM, you need to run PC-DMIS in Online mode. You also need to make sure the PC-DMIS computer can communicate with your CMM.

Offline programming techniques still work while in Online mode.

CMM Startup and Homing Procedure for PC-DMIS Online

1. If you have a CMM that requires air pressure, turn on the air to the CMM.

2. Power on the controller.

- Look for a large rotary switch, an on/off key, or a small rocker switch. The key or switch is likely on the controller mounted on the back of the CMM or workstation. Flip the switch or turn the key to start the controller.

- All of the LEDs on the jog box (hand-held controller with a joy stick) illuminate for about 45 seconds. After that time, several LEDs turn off.

3. Power on your computer and all of its peripherals.

4. Log on to your computer.

5. To start PC-DMIS in Online mode, from the Windows Start menu, locate the PC-DMIS 2019 R1 Online shortcut and click on it.

6. Once PC-DMIS opens, a message appears on the screen:

PC-DMIS MESSAGE:

Do a machine start (if needed), then press OK to home.

- On your jog box, press the button that starts the machine, for example: Mach Start, or Start. Hold it for several seconds until the LED illuminates. On some models, the button is here:

- The CMM needs to move to a home position. The home position enables it to properly set the machine's zero position and enable the machine's parameters (such as speed, size limits, and so on). Click the OK button in the above PC-DMIS message to home the machine. The CMM slowly travels to its home position. This position is the machine's zero position for all the axes.

WARNING: When you do this, the machine moves. To avoid injury, stay clear of the machine. To avoid hardware damage, run the machine at a slower speed.

Changing the Machine's Parameters

You can set numerous parameters to control the machine's speed and motion. If you need to change your machine's parameters, see "Setting Your Preferences" in the PC-DMIS Core documentation.
